Composite Ni/NiO-Cr2O3 Catalyst for Alkaline Hydrogen Evolution Reaction.
We report a Ni-Cr/C electrocatalyst with unprecedented mass-activity for the hydrogen evolution reaction (HER) in alkaline electrolyte. The HER kinetics of numerous binary and ternary Ni-alloys and composite Ni/metal-oxide/C samples were evaluated in aqueous 0.1 M KOH electrolyte. The highest HER mass-activity was observed for Ni-Cr materials which exhibit metallic Ni as well as NiO x and Cr2O3...
متن کاملMagnetoelectric Cr2O3 and relativity theory
Relativity theory is useful for understanding the phenomenology of the magnetoelectric effect of the antiferromagnet chromium sesquioxide Cr2O3 in two respects: (i) One gets a clear idea about the physical dimensions of the electromagnetic quantities involved, in particular about the dimensions of the magnetoelectric moduli that we suggest to tabulate in future as dimensionless relative quantit...
متن کاملReverse Micelle Based Formation of BaCO3 Nanowires
A reverse micelle based approach is reported for the synthesis of BaCO3 nanowires with lengths up to 100 μm and diameters as small as 10-30 nm, each of which is a continuous single crystal with the c-axis along the wire length axis. The synthesis is achieved by the reaction of barium and carbonate ions solubilized in the polar cores of nonionic reverse micelles of C12E4 (tetraethylene glycol mo...
متن کاملEvaporation of Cr2O3 in Atmospheres Containing H2O
Stainless steels in atmospheres containing H2O form a Cr2O3 scale in the early stage of oxidation. However, the Cr2O3 scale gradually degrades with time. In order to determine the effect of H2O on the deterioration of a Cr2O3 scale, evaporation behavior of Cr2O3 in N2-O2-H2O atmospheres was investigated. The rate of mass loss in a N2-O2-H2O atmosphere was found to be one order of magnitude high...
متن کاملthe relationship between critical thinking and reading strategies
during the process of reading, sometimes learners use ineffective and inefficient strategies and some factors may influence their use of strategies. perhaps critical thinking is one of these factors. this study aims to identify those categories of reading strategies that are mostly used by iranian efl learners and to see if there is any significant relationship between the critical thinking abi...
